OIL-FILTER.

vSpecif-icai-.ion of Letters Patent. Application filed June 1, 1907. Serial No. 876,964.

Patented June 1, 1909.

. To all whom 'it may concern:

Be it known that I, ALEXANDER WINION, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvementsl in Oil-Filters, of which the following is a specification, reference being had therein to the accompanying drawing. v

This invention relates to improvements in oil filters, for use in the oiling systems of automobiles, whereby the used oil escaping from the lubricated parts of the engine may be collected and forced through the filter to the oiling mechanism, and used over and over again.

In carrying this invention into practice the escaping oil isfcollected in the crank case of the engine and by means of a pump forced through the filter and to. the oil-distributin mechanism in a'mannerfull'y disclosed an described in my co-pending application, No.

368,700, April 17th, 1907.

In the accompanyin drawings, Figure 1, is a perspective view o my improved filter, the casing being broken away to disclose the interior construction thereof. Fig. 2, is a -central longitudinal sectional view of Fig. 1.

Fig. 3, is a transverse sectional view of my improved filter.

y improved filter consists of a suitable vertical casing 1, which is preferably rectangular in cross-section, as here. shown, and preferably vertically elongated, as also shown. In the use of this filter it is arranged in a vertical position, and connected to the automobile at a convenient and suitable position, l.and in any well known 'way to enable it to be attached and detached therefrom. The top 2 and fbottom'S of the casing are provided with a plurality of .openings or passage-ways 4, preferably parallel, ashere shown, which forms the intervening web-portions 5.

Placed of screens 6 which are preferably formed of metal and provided with, preferably, the edge frames 7 entirelysurrounding the screens and laced on both sides thereof. The edges of tiiese screens'and frames abut against opposite sides of the casing 1, while the top and bottom edges engage the inner sides of the web portions 5, and are suitably secured thereto, as by solder or otherwise at suitable oints, as indicated at a.

Suitab e detachable covers 8 are provided i cation.

within the casingl 1 are a plurality for the openings 3 and 4, and preferably placed between the covers and the top and bottom are suitable packings 9 for the purpose of making oil-ti ht joints'. These covers may be detachaby held in position in any desired manner, but, as here shown, they are secured by a suitable number of screws 10.

By reference to Fig. 2, it will be seen that the arrangement of the screens divides the casino into a plurality of parallel passageways Connected to the bottom of'one side of the casing, is an inlet orifice 11, and attached to the top of theopposite side of the casing is nected by means of a suitable pipe 13 with the ypum which takes the oil from the crank case an forces it into tlne casin as shown in thev aforementioned co-pen ing appli- The outlet orifice 12 is connected by means of a pipe 14 with the oil-distributing mechanism, as alsoshown anddescribed in the afore-mentioned co-pending application.

Attention is called to the fact that the passaveways b are free and unimpeded, and o. er no resistance to th'e flow of the oil through the filter, and that the filtering of the oil is accomplished solely by the screens. This leaves a plurality of passage-waysin which any sediment contained in the oil will AIn operation, the casing is full of oil, so that there is comparatively little .disturbance on account of the shaking of theautomobile.

' The top and bottom of the casing are provided with the openings located between the screens and the removable covers for the prpose of enabling the passage-ways to be readily flushed or cleaned out. By removthe opposite sides thereof is provided, whereby the screens may be cleaned by a fiushing, or by the use of a suitable scraper or brush, or by both.-

The oil supplying pump keeps the filter filled with oil, from which 1t passes to the oildistributing mechanism, which again delivers it to the parts to be lubricated, after which it is again collected and carried to the filter,

-thus making a continuous lubricating system thereof.

Forfacilitating the assembling of theparts,

the casing`is formed of sheet metal with the two sidesc, and the end d integral, while the ing the covers access between the screens and end e is made of a separate piece and soll dcred in position. The top and bottom 2 and 3 are also formed of separate pieces which are soldered in place This enables the screens to be placed in position and secured at suitable points a by solder.

Having thus described this invention,wh at is claimed, and desired to be secured by Letters Patent, is

l. A filter for lubricating systems of automobiles, of the character described, comprising a vertically-arranged casing, a plurality of parallel screensarranged therein and dividing the casing into parallel oil passages, the top and bottom of the casing having .openings between the screens, and removle covers for closing the said openings as i and for the purpose described.

2. A iilter for automobile lubricating systems of the character described, comprising a casing having parallel elongated openings in its top and bottom, a plurality of screens within the casing and arranged parallel the openings on the opposite sides t ereof, and removable covers for the openings, for the purpose described.

3. A ilterlfor automobile lubricating systems of the character described, comprising therein and dividing the casing into parallel oil passages, the ends of the casing having openings between. the screens, and remova le covers for closing the said openings for the purpose described.

In testimony whereof I aiix my signature in presence of two witnesses.
